[ng] distdir: verbatim inclusion of relevant makefile fragment

* lib/am/distdir.am: Rename ...
* lib/am/distdir.mk: ... like here, with related adjustments.
* automake.in (handle_dist): Include it using the 'verbatim'
function, rather than the 'file_contents' one.
* Makefile.am (dist_am_DATA): Adjust.
